Abstract:
The dataset includes records for 9 individuals from 1 species belonging to 1 family(ies), presenting 1 functional type(s), growing in 1 condition(s) within 1 major type(s) of habitat, with data included for the following variables:

| Pinus thunbergii | Pinaceae | evergreen gymnosperm |
Sampling strategy: Nine trees were felled in a Pinus thunbergii forest located in Ikunomatsubara, Kyushu University Forest. Sample trees were treated with the stratified clip technique by cutting them into parts contained in horizontal layers of 0-0.2 m, 0.2-1.2 m, and at intervals of 1 m upward. Stem, branches, and needles were separated.
Stem cross sectional area: Estimated from stem diameter.
Height: Method not reported.
Biomass: Measured fresh weight was converted to dry weight from the ratio of dry to fresh weights. Detailed method not reported.
Other variables: M.I. Ishihara, H. Utsugi, H. Tanouchi, and T. Hiura conducted formal search of reference databases and digitized raw data from Yi et al. (1989). Based on this reference, meta data was also created by M.I. Ishihara. Species name and family names were converted by M.I. Ishihara according to the following references: Satake Y, Hara H (1989a) Wild flower of Japan Woody plants I (in Japanese). Heibonsha, Tokyo; Satake Y, Hara H (1989b) Wild flower of Japan Woody plants II (in Japanese). Heibonsha, Tokyo.
This is how the study Yi1989 fits in the entire dataset (grey). each colour represents a species. A legend of species names with colours is included at the end for reports with 1 < n < 20 species.
